Consummate professionalism on the part of the crew and staff made the December 2015 Viking Alta Danube cruise a pleasure and an education. Opinions will differ as to the high points - Melk Abbey and the small town of Passau were mine. Ms Cornelia Svatek, our tour director was not only personable but extremely knowledgeable particularly on the culture and history of Bavaria and Austria - promote her to cruise director supremo, we say! Viking knows and respects its customers, sentiments which from our point of view at any rate, are reciprocated. Mike and Heather Buckingham, Wales, UK
